One main difliculty of the insecticide applicators presently in useinvolves the re-filling of the insecticide reservoir commonly attachedor made a part of the apparatus. In the past, the user, who is usually afarmer, rancher or stock feeder, has let the present type of applicatorecome ineffective as such because they permit the applicator to becomedry. The reason for this is primarily because of the diificulties inre-filling the apparatus, that'is, it takes considerable time andeffort, and further requires the use of special tools, re-filling cans,funnels and the like.

Hence, one main object of this invention is to provide in combination areplaceable cartridge containing insecticide which will permit the userto merely remove the empty cartridge, replacing it with a fullcartridge, thereby eliminating the objectionable features referred toabove.

Another object of this invention is to provide a cylindrical-typeapplicator which will house a cartridge-type filler and yet permit acontrolled flow of the insecticide over the entire outside area of theapplicator, resulting in eifective application of the insecticide to theanimal.

-A further object of this invention is to provide a means for suspendinga series of such cylindrical applicators so that a plurality of such canbe put into use from a single supporting foundation, in such a manner asto permit practically the entire outer area of said cylindricalapplicator to be available for contact.

A still further object of this invention is to provide a simple andpractical insecticide applicator of low cost, comprised of a minimumnumber of elements, each of which may be replaced by the userinexpensively.

Further objects and advantages of the invention will become apparentfrom a description of the apparatus itself, along with the accompanyingdrawing and claims.

FIG. 1 is a front view, showing the applicator along with its rigidframe construction.

FIG. 2 is a sectional view taken along line 2--2 and showing theinsecticide cartridge in place within the applicator.

FIG. 3 is a cut-away view of a portion of the bottom of said cartridgeshowing an opening covered by a blister seal.

FIG. 4 is a cutaway view of the inside liner 4 of the cylinder housingalso taken along part of line 2-2 show ing perforations or weep holeswhich permit the insecticide to escape outside the housing to saturatethe absorptive material around which the wire mesh has been placed, saidview considered with the cartridge 6, absorptive material 3, and wiremesh 14, all removed.

Like characters of reference indicate like parts in the ditferent viewsin the drawing.

Turning first to FIG. 1 of the drawing, a metal strip or angle iron 7has been welded to two metal rings 8 and 9. These rings 8 and 9 are madeout of heavy gauge metal of sufiicient size to permit the housing of theentire cylinder. In order to prevent the cylinder from slipping, a metalstrip 12 has been brazed or welded across the diameter of the metal ring8.

Turning now to FIG. 2, it will be noted that a hollow metal cylinder 4of suflicient diameter to permit the cartridge 6 to be inserted, hasbeen used as a form around atent "ice which an absorptive material 3,such as pressed felt, has been wrapped. This absorptive material may bespot glued to secure it to the outer portion of the hollow metalcylinder 4. Around the absoptive material 3 has been placed a heavy wiremesh 14, which may be securely fastened by tie wires, spot welding orother satisfactory conventional means not shown. This wire mesh 14should be snugged tight across the absorptive material 3 to prevent anyslippage or movement between the absorptive material 3 and the wire mesh14.

Around the inner periphery of the hollow metal cylinder 4 and adjacentthat end adjacent the metal ring 9 has been placed a suitable thicknessof absorptive material 5, similarly of pressed felt or other suitablematerial, which may be glued, the purpose of such absorptive material 5being more particularly set forth hereinafter.

The end of the hollow metal cylinder 4, adjacent the metal ring 8, hasbeen scaled completely. The Walls of said hollow metal cylinder 4 have aplurality of weep holes 11 which may be approximately A to $4; inch indiameter and located within the middle of said cylinder, as moreparticularly shown in FIG. 4 of the drawing. These weep holes 11 extendcompletely around the hollow cylinder 4 within this middle two-thirdsarea, so that when an animal rubs against the applicator so as to causethe entire applicator to swing in an arc, the insecticide will flowcontinuously out of the weep holes. As will be seen hereinafter, whenthe insecticide escapes from the cartridge 6, it will flow into the openarea between the outside wall of the cartridge 6 and the inside wall ofthe hollow metal cylinder 4. It should be recognized that each end ofthe metal strip 7 from which the applicator is suspended is attached toany commonly known type of swivel connection which would permit I radialmovement of the entire apparatus. As stated, it is the inventorsconception that a plurality of these applicators could be used and wouldbe suspended by a single common metal strip such as the strip 7. In anyevent, the insecticide inside the cartridge 6 will flow out into theinside wall of the open area as stated. This insecticide will thenescape through the Weep holes in the cylinder 4 directly to theabsorptive material 3, thus saturating the absorptive material, whichwill permit effective application of the insecticide upon any animalmaking contact. The insecticide inside the cartridge will continue toflow into the area between the hollow cylinder 4 and the outer wall ofthe cartridge 6. It will in turn flow out the weep holes until the fluidlevel is almost exhausted, and it is believed that the movement of theapparatus, actuated by an animal brushing against it, will be sufiicientto keep the insecticide in agitated movement so that it will draincompletely in the fashion described. The wire mesh 14 has a two-foldpurpose, in that it keeps the absorptive material intact and scratchesthe hide of the animal.

The replaceable insecticide cartridge 6 is made of a thin wall metal orplastic completely sealed at both ends, however, the bottom end of thecartridge has one or more holes 13 to permit the insecticide to flow outof the cartridge in the manner aforesaid. I prefer at least two holes sothat during the cold season, twice as much area will be available forthe insecticide to flow, whereas in the warm season only one hole willbe used. This preference is based on the fact that the insecticideduring the cold season has a high viscosity and the flow will besomewhat impeded.

In order to permit the insecticide cartridge to be portable withoutdanger of leaking, these holes have been covered by a blister-likecovering 10, which may be of wax, paraffin, plastic or some othersuitable material which may be removed with a scraping of the fingernailwhen the cartridge is to be inserted for use. One end of the cartridge 6has a flanged portion 15 which, when the cartridge is inserted, fitssnugly against the absorptive material 5 located on the inner portion ofthe hollow metal cylinder 4. This serves two purposes, in that the tightfit between the above elements will retain the cartridge in place andalso prevent the insecticide from flowing in any other manner thanthrough the perforations 11. There will be some saturation of thisabsorptive material 5, however, it has been experienced that suchsaturation will nowhere be complete during the time required forcompletely exhausting all insecticide out of the cartridge 6 and ontothe absorptive material 3.

In the illustration shown in the drawing, which has been put in actualpractice, no fastening device is necessary if the cartridge 6 fitssnugly against the absorptive material 5 lining the inside of thecylinder 4.

Having thus described one illustration of our invention, along with thecomponent features and elements thereof,

it should be understood that the above description is meant for purposesof describing and illustrating the invention in the best possiblemanner, but is not meant to limit its features in any way, as variationsof the structure may be made within the scope of the claims.
